The President of the Autonomous Bougainville Government in Papua New Guinea is seeking a stay on the issue of writs for the upcoming ABG elections.
The Post Courier newspaper reports John Momis has filed a Supreme Court reference.
He wants the election to be delayed pending the court's interpretation of laws he alleges ABG speaker Simon Pentanu may have tampered with.
The reference asks the courts to interpret whether or not representatives of former combatants were eligible to vote on a proposed amendment of the Bougainville Constitution.
The issue surrounds a house vote on the matter which Mr Pentanu oversaw and claimed fell short of the needed absolute majority of 27 needed.
Mr Momis challenges the speaker's decision on the grounds that at the time, an MP's seat was vacant, due to his death, a few weeks before the vote.
